In the previous post, I plan to use some "novel" multireference methods that can treat huge active spaces (up to 50 active orbitals). I now decide to adopt the first baby: the variational two-electron reduced-density-matrix (2-RDM)-driven complete active space self consistent field (v2RDM-CASSCF). Why? Because Fun fact: in the paper, DePrince wrote “the chemistry community has… Continue reading Adopting a new baby – v2RDM-CASSCF→

Over the years, developing or benchmarking DFT functionals has been a hot topic, for example D. Truhlar paper on M06 has reached over 9000 citations, or this paper of D. Jacquemin on (just!) TD-DFT benchmark of organic molecules receives more than 500 citations. This leads to a zoo of DFT functionals, and it's growing wild like weed.… Continue reading Multireference methods – a review (part 1)→
